Answer 1

Answer:

123

Step-by-step explanation:

Squaring the given equation gives

[tex]t^2+(2\cdot t \cdot \frac{1}{t} )+ \frac{1}{t^2}=9.[/tex]

The [tex]t[/tex] and [tex]\frac{1}{t}[/tex] terms cancel out nicely, which is one of the reasons for squaring the equation.

Simplifying gives

[tex]t^2+2+\frac{1}{t^2}=9,[/tex]

[tex]t^2+\frac{1}{t^2}=7.[/tex]

The question asks for [tex]t^5+\frac{1}{t^5},[/tex] so we can square the equation again and simplify to get higher powers into the expression:

[tex](t^2+\frac{1}{t^2})^2=49,[/tex]

[tex]t^4+(2 \cdot t^2 \cdot \frac{1}{t^2}) + \frac{1}{t^4}=49,[/tex]

[tex]t^4+2+ \frac{1}{t^4}=49,[/tex]

[tex]t^4+\frac{1}{t^4}=47.[/tex]

Multiplying this expression by [tex]t+\frac{1}{t}[/tex] to try and get a fifth power gives

[tex](t^4+\frac{1}{t^4})(t+\frac{1}{t})=t^5+t^3+\frac{1}{t^3}+\frac{1}{t^5}.[/tex]

The only thing left we need is [tex]t^3+\frac{1}{t^3}[/tex] to subtract from this; we know everything else. Since [tex]t^3+\frac{1}{t^3}[/tex] can be written as [tex](t+\frac{1}{t})(t^2-1+\frac{1}{t^2}),[/tex] we can simply plug in the values we know for [tex]t+\frac{1}{t}[/tex] and [tex]t^2+\frac{1}{t^2}:[/tex]

[tex]t^3+\frac{1}{t^3}=(3)(7-1)=18.[/tex]

All that is left is to plug it in our equation here:

[tex](t^4+\frac{1}{t^4})(t+\frac{1}{t})=t^5+t^3+\frac{1}{t^3}+\frac{1}{t^5},[/tex]

[tex](47)(3)=t^5+\frac{1}{t^5}+18,[/tex]

Multiplying and rearranging gives:

[tex]t^5+\frac{1}{t^5}=123.[/tex]

Answer:

no solution

Step-by-step explanation:

-2y-3y+8=8-5y-12

-2-3y=-5y

-5y+8=8-5y-12

inverse operation: add 5y to both side

-5y+8=8-5y-12

+5y        +5y

-5y+5y=0, so it cancels out both -5ys

8=8-12

8=-4

there is no value for y to make the equation true, so there is no solution

By using the definition of collinear and coplanar points, we will see that

7) Collinear points: All lie on the same line.8) Coplanar points: All lie on the same plane.What do collinear and coplanar mean?

We say that a given set of points is collinear if all the points belong to the same line, just to give an example, any pair of two points is collinear, as we always can find a line that passes through two points.

On other hand, a set of points is coplanar if the points lie on the same plane. Remember that a plane is defined by a line and a point outside of it.

With these definitions in mind, we can answer:

7) Collinear points: All lie on the same line.8) Coplanar points: All lie on the same plane.

What is the equation of the line that passes through the point (3,−3) and has a slope of 0?

Answers

Answer:

x = 3

Step-by-step explanation:

A line with a slope of 0 is a horizontal line parallel to the x- axis with equation

x = c

where c is the value of the x- coordinates the line passes through.

the line passes through (3, - 3 ) with x- coordinate 3 , then

x = 3 ← equation of line

Answer:

f(x) = -3

Step-by-step explanation:

it will be a constant function because if the slope = 0, the y value is not changing

so the equation of the line, f(x) = ax+b, will be f(x) = 0x+b

f(x) = b, b is the y value here

A camera has a listed price of $801.99 before tax. If the sales tax rate is 8.5%, find the total cost of the camera with sales tax included.

Round your answer to the nearest cent, as necessary.​

Answers

Answer:

$870.16 dollars

Step-by-step explanation:

Given the following question:
Original cost = $801.99
Sales tax of 8.5%

In order to find the answer, we find 8.5% of the original cost of the camera. After that, we simply add that number to the original cost of the camera to find our answer.

[tex]\frac{8.5\times801.99}{100} =8.5\times801.99=6816.915\div100=68.16915[/tex]
[tex]68.16915[/tex]
[tex]9>5[/tex]
[tex]68.17[/tex]

Sales tax is $68.17

[tex]801.99+68.17=870.16[/tex]

Total price for the camera including tax is "$870.16."
